The worst customer service experience I have ever had. I purchased a pair of AF'1's from first step about three months ago that were two big. At first the clerk stated that it was not problem and that I could get store credit because the shoes were never worn. Then changed his mind. I stated that I was a Native San Franciscan and I had been buying shoes since the mid 80's at the upstairs location on Powell and that they would lose a loyal customer. I WAS TOLD THEY DIDN""T NEED MY BUSINESS!?
